Rapid Shutdown Kit - Installation and Configuration

(Single Phase Inverters)

This document describes how to install the rapid shutdown kit in the SolarEdge Safety Switch, and how to enable the rapid

shutdown feature in the inverter in order to provide the functionality described in the Rapid Shutdown clause of NEC2014

690.12 (1) through (4).

Kit Contents

§ Rapid shutdown cables

§ (Optional - For older inverters only) Micro-SD card and SD card adapter with firmware files (Note: DO NOT THROW AWAY

THE CARD AND THE ADAPTER; keep them for installation of other rapid shutdown kits)

Cable Installation

Perform this procedure before connecting the strings to the Safety Switch [Chapter 4: Connecting the AC and the Strings to the

Safety Switch in the SolarEdge Installation Guide].

1 Turn the inverter ON/OFF switch to OFF. If installing the kit in an inverter that is already operating, wait until the LCD

indicates that the DC voltage is safe (<50V), or wait five minutes before continuing to the next step.

2 Turn the Safety Switch and the AC switch on the main circuit board to OFF.

WARNING!

If you cannot see the inverter panel, or if a malfunction is indicated on the LCD panel, wait five minutes for the input

capacitors of the inverter to discharge.

3 Loosen the four Allen screws on the front cover of the Safety Switch, and open the cover.

4 Carefully disconnect the two DC cables from the left side of the switch and from the DC connection spring clamp terminals,

as illustrated below

. Use a standard straight-bladed screwdriver to disconnect the cables from the terminals.

The internal components may vary depending on the Safety Switch model; the figures in this documents show the AC/DC Safety Switch for single phase

7.6-11.4 kW inverters.

Connect these ends to the switch, making sure that the red and black cables are reversed relative to the cables connected at the top of the switch (going into the DC side conduit between the inverter and the Safety Switch), as detailed below.

Rapid Shutdown Kit - Installation and Configuration (Single Phase Inverters) Inverter Software Compatibility Check and Upgrade Perform this procedure after activating the inverter [Step 1 in Chapter 5: Commissioning the Installation of the SolarEdge Installation Guide], and before pairing (Step 2 in Chapter 5 of the SolarEdge Installation Guide). To use the rapid shutdown feature, the inverter communication board firmware (CPU) must be:   Version 2.0700 or higher, if the CPU version is 2.
